Please help... :)
Booby wants to hang a rock from his ceiling. Bobby finds his Dad's fishing line in the basement. One line says 15-lb test meaning it can hold 15.0 pounds but maybe not more. The other line says 50-lb (same assumptions). (Label the strings T1 and T2). He attaches the strings to the ceiling. What is the heaviest rock Bobby can hang using the two strings?
What is T1 (string 1)?
What is T2 (string 2)?
What is W (rock)?
